Analyzing Non-Extensivity of $η$-spectra in Relativistic Heavy Ion Collisions at $\sqrt{s_{NN}}=200$ GeV
The transverse momentum spectra of secondary $η$ particles produced in $P+P$, $D+Au$ and $Au+Au$ interactions at $\sqrt{s_{NN}}=200$ GeV at different centralities have been studied in the light of a non-extensive thermodynamical approach. The results and the possible thermodynamical insights, thus obtained, about the hadronizing process have also been discussed in detail.
